IMPROVEMENT IN PAPER-RULING MACHINES Specification forming part ofLetters Patent No. 155,515, dated October 13, 1874; application filedSeptember 3, 1874.

To all whom it may concern:

Be it known that I, JAMES TREGURTHA, Of

Boston, in'the county of Suffolk and State of mechanism of apaper-ruling machine which controls the action of the pens, and usuallycalled the striker, and it consists, first, in

i the use of a wheel mounted upon an axis parallel to the axis of thestring or driving-cylinder, and arranged to be driven by exteriorcontact with the periphery of Said cylinder, and provided withadjustable cam-blocks fitted to and secured in grooves formed inv theinterior periphery of the rim of said wheel as a means of controllingthe action of the pens, I

My invention further consists in the combination, with a cam-wheelconstructed, arranged, and operated as above set forth, of a stop or lugsecured thereto, a pawl-lever arranged to be interposed in. the path ofsaid lug, and a latch-lever to lock said pawl-lcver in position, andsuitable devices for tripping said latchlever to release said wheel, andallow it to revolve at the proper time.

My invention further consists in the use, in combination with a wheelprovided with adjustable cam-segments, of a cam-lever made in two parts,and secured together by means of an axial clamping-pin, so as to form arigid lever, one portion of which may, by loosening said axial pin, beswung to one side in a plane at right angles to the plane of movementsof said lever, when acted upon by the cam, to facilitate the removal ofthe cam-wheel, and the substitution of another of different size, whichbecomes necessary as oftenas the size of the paper to be ruled ischanged.

the pen-beam is vibrated to lift the pens from the paper at the propertime.

My invention further consists in attaching the pen-beam lever to saidbeam in such. a manner that it may be adjusted about the axis thereoffor the purpose of adjusting the lift of the pens; and it furtherconsists in constructing said lever with a broad pad or table-likesurface at its outer end, to receive the end of the set-screw in the endof the camlever, so as to allow of any desired amount of adjustment ofthe end of the pen-beam Without breaking the connection between the twolevers.

My invention further consists in the appli cation of a similar pad ortable to the outer or movable end of the lever, which operates therocker-shaft, through which the latch-lever is depressed to release thestop-pawl, and allow the cam-wheel to revolve. Upon this pad rests theend of a set-screw attached to the movable end of a lever, firmlysecured to .a rocker-shaft above the pen-beam, from the opposite side ofwhich projects another lever or arm, to the movable end of whichis\sccured, upon a suitable axial pin, the ordinary trip-wheelforreleasingthe cam-wheel.

My invention further consists in giving to the trip-wheel more lift thanis required to release the cam-wheel, and varying the time of suchrelease by interposing between the trip-wheel and the latch-lever thatlocks the cam -wheel an adjustable point of contact in the shape of theset-screw last referred to.

My invention further consists in fitting said screw in a nut pivoted tothe end of the rocker-shaft arm, so as to swivel therein, the axis ofsaid nut being at right angles to the axis of the screw, in combinationwith a fixed guide, through which the lower end of said screw passes,said screw being raised or lowered to vary the time of the pens strikingthe paper.

In the drawings, Figure 1 is a plan of so much of a paper-ruling machineas is necessary to illustrate my improvements. Fig. 2- is a verticaltransverse section on line w w on Figs. 1 and 3. Fig. 3 is a sideelevation of the lustrating the construction of' the cam-lever and itsrelation to the pen-beam lever, as well 7 is a plan of a portion of thetrain of mechan-' ism for operating the latch-lever to release thecam-wheel. l

A A is the frame of the machine; "B, the cloth or apron cylinder; 0, thepen-bearing cylinder; and D, the apron-roll, mounted in bearings, madeadjustable by means 'of the 3 screw-nuts a a, all constructed andarranged in a well-known manner. E is the paper-carrying cloth orendless apron. .F is the stringcylinder, mounted upon the driving-shaftF. G and G are the stringguide rolls, around which and the cylinder Fare led the endlessstring belts b b, in the usual manner. 'H is adisk-wheel, mounted upon a stud, 0, set in the movable end of theradius-arm I, arranged to vibrate about its fulcrum-pin, to adapt itsposition to the size of the cam-wheel being used. The wheel H must havean exterior circumference about equal to the length of the piece ofpaper to be ruled, and is provided with a heavy projecting rim, H, uponone side, in the inner face of which are formed two grooves, d and d, ofunequal depths, in which may bein- 'serted one or more segmental piecesof metal, '6 0, so formed as to project beyond the inner periphery ofthe rim H a distance equal to the movement that it is desirable toimpart to the cam-truck for lifting the pens from the paper. Thesesegments are held in position by the setscrews f and f, the screw fbearing against the segment in the groove d, and f against the segmentin the groove (1 said screw passing through solid metal below the bottomof the groove d and the segment contained therein, as seen in Fig. 2.The wheel H rests upon the periphery of the string-cylinder F, and isforced against it by the spring J or a weight with sufficient force tocause it to be revolved thereby when not prevented by the stop. K K is acam -lever, made in two parts, connected together by the axialclamping-boltg, so as to form a rigid lever, and mounted upon thefulcrum-pin h, set in the stand L in a horizontal position, parallel tothe axes of the wheel H and the string-cylinder F, and at right anglesto the axial pin g, which secures the two parts K and K of said levertogether. The mov-, able end of the part K'of said lever is providedwith a stud, i, set rigidly therein, and projecting therefrom parallelto the fulcrumpin it, and upon which is mounted the camtruck j, arrangedto rest upon the inner periphery of the rim H of the wheel H, or the"segments 6 e set therein, said truck being located between the axis ofthewheel andthe point of contact of said wheelwith the periph cry of thestring-cylinder. The opposite mov- "able end of the lever K K isprovided with pens to the work.

of the pen-beam M. The lever l is mounted loosely upon the threadedjournal'shaft m, and may be adjusted about said journal and secured inany desired position by the screw n andnut '5, fittedt-o and moving inthe slot p formed in the plate q, secured permanently to the end of thepen-beam M, as seen in Fig. 4. The pen-beam Mis made in two parts,secured together by the screws W, and has permanently attached to oneend thereof the smooth journal-shaft s, and to the other end the plateq, in which is journaled so as to revolve therein the threadedjournal-shaft m, said shaft being so fitted to the plate q that, whileit may revolve therein, it cannot be moved endwise therein. N and N aretwo stands, in which the penbeam M is mounted by means of thejournalshafts m and s, the stand N being provided with a femalescrew-thread to fit the thread on the journal on, so that,by revolvingthe journal-shaft m, by means of the milled headv t attached to itsouter end, the pen-beam M may be moved endwise to adjust the penslaterally upon the paper being ruled. The stand N is secured to the topof the frame A by the screw u, and the stand N is secured to the plate 0by means of the thumb-nut P and a headed bolt passing through a slot insaid plate, with the head below the plate, in a well-known manner, sothat said stand may be adjusted in the direction of the length of themachine, for the purpose of squaring the Q is a rocker-shaft, mounted inhearings in the upper part of the stands N and N, directly over thepen-beam M; and It and R are levers firmly secured thereto, andprojecting from opposite sides thereof, as shown. The lever B isprovided with a stud, 11, upon which is mounted the trip-wheclS, havinga portion of one side cut away, so as to fit or nearly fit the curve ofthe pen-bearing cylinder, upon which it rests, with the endless apron Einterposed between, and provided with the small projecting tooth o,against which the sheet of paper strikes 'as it is carried forward bythe endless apron E and string-bands b b, and by the continuedforwardmotion of thepape'r said wheel is revolved, which raises thelever B, rocks the shaft Q, and depresses the outer end of the lever B.

The'lever R has pivoted to the side of its outer end the nut 10, throughwhich passes the screw w, and in which it may be adjusted to vary the'distaucebetween its lower end and the lever a rigidly secured to therocker-shaft 12*, upon which it strikes when the lever B is depressed. yI

This adjustment is of great advantage, as

admitting of a much finer adjustment of the the'guide a projecting fromthe stand N, and? the swiveling attachment of the nut w allows a freemovement of the lever B through the:

arc of a circle without causing the screw w to bind in its nut. Themovable end of the lever a 'is expanded into the form of a broad, pad,upon'which the end of. the screw w .will' strike when it descends, intowhatever-position the pen-beam may beadjusted; and said lever is heldup, when the, pressure is removed, by the spring a. m M v r 1 \r Therocker-shaft b is mounted in bearings, in the stands 0 0 secured to theplate 0, and has secured to its end, opposite the lever a another lever,(1 projecting therefrom, upon the same side as a the movable end ofwhich rests upon one end of the latch-lever 6 provided with the shoulder0 and pivoted at c to the stand f as seen in Fig. 6.

g is a stop-pawl, pivoted to the stand it, the long arm of whichdepeudsfrom its fulcrum-pin, and rests upon the latch-lever 0 just forwardofthe shoulder 0 while its short arm is maintained in a position to bestruck by the dog orlug 11 secured to the face of the rim H of the wheelH, as seen in Figs. 3 and 6.

The lever e is provided with a counterpoise-arm, 0 which causes thelatch to operate by the force of gravity, and the same force causes thestop-pawl g to assume a position to be latched after it has beentripped.

T T are gear-wheels, by which motion is imparted from thedriving-cylinder to the cloth or apron cylinder; and U is a crank, bywhich the machine is operated.

A great advantage is gained by the use of my improved cam-wheel,arranged as set forth, from the fact that any desired diameter ofcam-wheel may be used without change in, or adjustment of, other partsof the mechanism, the cam-truck j on the end of the lever K'alwasfbearing the same relation to the point of contact of the wheel H withthe string-cylinder; and, if the rim H of all the cam-wheels is made ofthe same radial width,

it follows that a wheel of any desired diameter may be' substituted forthe one in use without changein other parts of the mechanism, except to,swing the radius-arm I into the proper position to bring the lower edgeof the cam-wheel into contact with the periphery of the string-cylinderF, as described.

The peculiar construction of the lever K K is for the purpose offacilitating the changing of the cam-wheels, which is done by looseningthe axial bolt 9 and swinging the arm K with the truck j away from thecam-wheel H, when the camwheel, together with its supporting-arm -1, maybe raised, it necessary, and the wheel H be withdrawn from its stud, andanother wheel of difl'erent diameter put in its place, when the arm K isagain swung into position parallel to the face of the cam-wheel, withthe truck j above the rimjH, and the axial clamping-bolt is screwed downhard,-'when the machine is again ready for operation.
